👤 whose
Whose observations first revealed the existence of isotopes?
Quick Answer
Frederick Soddy showed that elements could exist in different atomic forms with the same chemical behavior. His isotope concept was introduced in the 1910s.
The Full Story
British chemist Frederick Soddy helped establish the idea that atoms of the same element can have different masses, now called isotopes. He introduced the term 'isotope' in 1913. This insight was vital for radiometric dating because isotopes decay at known rates. It also transformed nuclear physics and geochemistry.
Key Facts
1.Soddy introduced the term in 1913
2.Isotopes are atoms of the same element with different masses
3.Radiometric dating depends on isotope decay
